No Go

Took my 1965 American Skier out for my first run. 1964 260 Interceptor engine and I believe it’s a Borg Warner Velvet tranny??? Was running great, on plane and moving along. All of a sudden, lost propulsion. Engine running fine. Boat wouldn’t go in reverse or forward. Shift cable is fine and moves the armature. Prop still on the shaft and looks to be keyed properly. Didn’t make any noise or anything. Luckily had paddles to make it back to ramp. Also asking on Facebook pages maybe some of same guys here too. Fluid seemed a little low, so added half a quart (now about 3/4” above full cold and sitting). Going to try it out again today at the ramp. Any ideas form any guys here on why it would be going sting and just give up like that with no indications anything was going wrong? Is there a shear pin somewhere? Thanks!

If you added fluid and it was still "No Go" (FB info)and you're thinking it might be the pump or the pressure control valve, it's pretty easy to check the pressure while the transmission is installed in the boat with a gauge and a few fittings fittings.

The control valve can be removed/inspected/replaced with the transmission installed in the boat if that's suspected to be the issue.

There's a spring inside the valve that controls pressure unless it's broken

Hope the problem is simple to fix. A failed damper will do what you've described but isn't a simple fix.

And thanks for all the help everyone!

My dipstick is metal and on the right side with the shifter on the left. One of the cooling lines comes in the top and there is a "vent" on top. Looks different than that picture. I took video of the trans barely moving while in gear. I'll grab a screen shot fo the top of trans to help with the model ID.

Greg,
I can't get to your pictures even after copying and pasting in my browser. Maybe someone else can or, you could try posting them?

Greg,
Found the person who works on the Dearbo's:

Keep it original?

Would a rebuilt velvet drive be a "drop in" replacement with just needing to route the cooler lines? Or is the spacing way different requiring a different drive shaft, coupling, etc.

Gary,
I'm hearing that with all the stay at home orders that the internet is at a peak nearing overload. It's pretty common for my Frontier service to "overload" and I'm told it's due to one of their servers going down and then others needing to pick up that traffic. Today when I copied and pasted the flickr, it simply would not load. I tried it several times!   

If I were to buy a rebuilt Velvet and bell housing would it be pretty much drop in, bolt up, hook up/adjust linkage, hook up trans cooler lines, and good to go? I have worked on cars a lot, but never on a boat so "spacing" concepts in a boat are new to me.

I guess it's a good thing I posted a picture of a Borg Warner transmission

You might want to do some research on bellhousings before just getting what you think is right.

Since you say you have a 260, it would have the early SBF bellhousing bolt pattern with 5 bolts holding it on. Most later stuff has a different pattern with 6 bolts

They're a little hard to find these days for a marine application unless what you have now has the same transmission mounting pattern you could use that.

You'd maybe need a new damper plate to go along with everything else and maybe some new transmission mounts.

It won't be the simplest of "swaps"

A good thing to remember is that any talk of pressure control valves etc or any suggestions by people was before you figured out it wasn't a Borg Warner.

Talking to Jim is your best bet

Here's some reading in the link below

But... But Pete

That didn't answer my question

How about things like your fuel pumps, carburetors, starters, alternators/generators bilge blowers etc?
